Bart Van Assche aa726929fa ib_srpt: Handle GID change events properly 
The mlx4_core driver generates a GID change event after a port has been
changed from IB into Ethernet mode. Avoid that this causes the following
error message to appear in the system log:
    
ib_srpt: ***ERROR***: received unrecognized IB event 18

Bart Van Assche 858d02e558 [PATCH] ib_srpt: Always set RSPVALID flag in task management replies 
The SRP spec requires not only to set the RSPVALID flag and the RSP_CODE
field if a task management function failed but also if it succeeded. This
patch avoids that the SRP initiator interprets task managment functions
that succeeded as failed.

Vladislav Bolkhovitin 6e31fd8306 Relax and cleanup HARDWARE ERROR sense usage 
HARDWARE ERROR sense is very strong considered be "internal failure", so
might lead to serios initiator side issues up to disconnect from device. In
many cases WRITE or READ ERROR sense can be used instead. All remaining
usages must be logged.

Vladislav Bolkhovitin 2093dd7561 Make it possible to forcibly close SRP and FC sessions via sysfs 
That patch contains the following changes:
* Move the code for creating a "close_sess" sysfs attribute from iscsi-scst to
  the SCST core such that it becomes available for other target drivers. This
  does not change the functionality of iscsi-scst.
* Add code in ib_srpt and qla2x00t to allow a session to be forcibly closed from
  user space.
